Don't install example scripts
Don't install example scripts

This can either be accomplished by:

A) making the scripts directory not be a Python module by removing the
`__init__.py` file, or

B) add `scripts` to the `excludes` parameter of `find_packages()` in
setup.py.

Since the there is no reason the scripts directory needs to be a Python
module, I went with A.
